KX3 CW from computer
Locked
 
|
I have been re-reading the manual and posts on this subject, and I am
getting a bad feeling. I hope I am misunderstanding what I'm reading, but if not, the KX3 can't be keyed by a computer via the normal means of having the software assert RTS or DTR. If the KX3 won't do CW from a computer without an additional external gadget its suitability for DXing, FD, Sweepstakes, and other contests will be seriously hampered. Most FD or DXpedition ops might leave it at home and just take a K3. The solution proposed so far is to make a serial cable with a key plug hanging off it, plug that into the key jack, and configure the KX3 to see it as a straight key. Then to use a paddle, you'd need a Y-connector at that jack and an external keyer. I have actually had a setup like this, so I have the external keyer and the Y-connector, but it is not elegant to say the least. Much better would be to design the appropriate capability into the KX3. To many hams, a 10w radio is primarily a CW radio, so this really needs to be addressed, i.e. the DTR or RTS lines have to be available and capable of keying the KX3. I hope that I'm just overlooking something obvious and that the actually KX3 has the proper functionality and I just don't understand it.

When I started having the poor keying due to Windows being busy not and
then, I changed over to using a USB WinKeyer, so this is just not a problem for me. This gives me both clean keying with the computer and lets me have the paddles to use too. In the field, I'll not have a computer and will just use the internal keyer. So for me, not being able to key via the Serial port is not important.

Won't there be some sort of "TERMINAL" in the KX3 utility that will allow the KX3 to
be keyed from the computer? I just discovered that was possible for the K3 ;-) VY 73, Lance On 3/12/2012 4:21 PM, KU7Y [via Elecraft] wrote: > When I started having the poor keying due to Windows being busy not and > then, I changed over to using a USB WinKeyer, so this is just not a problem > for me.

The KX3 could be keyed from RTS or DTR via the either its KEY jack or the GPIO pin of the ACC2 jack. You'd need to split the keying signal out and supply one or two external components, depending on the Signal levels.
Note that the KX3 is *not* primarily a CW rig. It handles all modes, including nearly all of the voice-mode features of the K3.

Yes, the KX3 Utility has the same capability.

While the KX3 Utility's Terminal program uses the K3 or KX3's command set
(specifically the KY command), I don't believe many of the popular contest logging programs exploit this Elecraft-specific capability. Instead contest logging programs tend to use a technique that works for almost all radios: Wiggle a serial port modem control pin (DTR or RTS), or a parallel port pin (a popular technique before Windows made it difficult to get programmatic access to a parallel port pin without installing a specific device driver), or through commands sent to a K1EL Winkey chip (or an emulation of that chip). >From the radio's perspective, all of these amount to toggling the "straight key" line. There may be contest or general purpose logging programs that I am not aware of that do exploit the K3/KX3 KY command. It would be a nifty software development opportunity for a logging program on a NetBook sized computer to use just one serial port connector to the KX3, and use its serial KY command for CW keying. But I don't think we are there yet. I'd like to be wrong. 73 de Dick, K6KR -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Tony Estep Sent: Monday, March 12, 2012 10:02 AM To: Elecraft Subject: [Elecraft] KX3 CW from computer On Mon, Mar 12, 2012 at 11:35 AM, W7GJ, Lance <[hidden email]> wrote: > Won't there be some sort of "TERMINAL" in the KX3 utility that will > allow the KX3 to be keyed from the computer?... ======== Lance, if I'm reading the posts and the manual correctly, it's not a software issue.

I do not believe there is a need for 2 com ports.
Most logging applications only handle 1 port. They use TXD and RXD for rig control and do keying and PTT with RTS and/or DTR in the same port. All you need in addition to the KX3SER cable is to make two of the "one transistor keying circuit" to convert the RS-232 levels to TTL - connect one circuit to the RTS pin, the other to DTR (in the same KX3SER cable). on the KX3 side of the 2 circuits, one connects to the hand key input and the other connects to PTT. Actually, you will probably want to make your own KX3SER cable because the production cables will have a molded backshell according to a post by Eric last week - but making your own should not be difficult at all, a male DE-9 connector, a backshell, a 3.5mm stereo plug and some wire - add 2 transistors for the one transistor keying circuits and you are done. 73, Don W3FPR On 3/12/2012 12:51 PM, Tony Estep wrote: > On Mon, Mar 12, 2012 at 11:18 AM, KU7Y<[hidden email]> wrote: >> ...I changed over to using a USB WinKeyer... > ======== > I can set up my software to use 2 Com ports, one for > rig control and one for keying, and have a second gadget attached to > the computer to key the radio. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I would also like to see something like this, but there are a few
obstacles to overcome: - I don't think there are many rigs out there that implement direct alphabetic keying via their CAT interfaces. - I've looked for an API for such a facility in hamlib, the major multi-manufacturer/multi-rig interface programming library, and I was not able to find it. This means that if you want to make use of the KY command, you will need to write your own rig interface code, which is a lot of overhead. - The added delays of sending the KY command over the serial port, and then having the rig interpret and execute the command, might be a bit too long for some ops to tolerate. Toggling a serial port pin is faster -- it's just not the "right" way to do it. 73, Andy, N2CN On Mon, Mar 12, 2012 at 1:29 PM, Dick Dievendorff <[hidden email]> wrote: > While the KX3 Utility's Terminal program uses the K3 or KX3's command set > (specifically the KY command), I don't believe many of the popular contest > logging programs exploit this Elecraft-specific capability. > > Instead contest logging programs tend to use a technique that works for > almost all radios: Wiggle a serial port modem control pin (DTR or RTS), or > a parallel port pin (a popular technique before Windows made it difficult to > get programmatic access to a parallel port pin without installing a specific > device driver), or through commands sent to a K1EL Winkey chip (or an > emulation of that chip). > > >From the radio's perspective, all of these amount to toggling the "straight > key" line. > > There may be contest or general purpose logging programs that I am not aware > of that do exploit the K3/KX3 KY command. > > It would be a nifty software development opportunity for a logging program > on a NetBook sized computer to use just one serial port connector to the > KX3, and use its serial KY command for CW keying.

If I'm reading the manual right, there is no need for PTT when using CW.
Set the transmitter keying method to VOX and it will key without needing to use the PTT line. If you set the break-in delay (DLY) to 0, (zero), you will have full QSK. I have no idea how the 100w amp will work. IMHO it should be able to do full QSK but time will tell......

> I do not believe there is a need for 2 com ports.... =========== In general you're right, Don, but in my case I will. To key the KX3 with my external keyer I have to address the keyer on its own Com port. My software allows for CAT on one port and keying or PTT on another, so it's not a problem. It's just sort of an ugly solution to have to use an external keyer and additional port -- and my keyer is not that much smaller than the KX3. The KX3 already is using one 4-conductor 1/8" plug. A plausible way around this would have been to use the same thing on the computer cable so that DTR could be present. Then PTT could be available for digital programs, too. I guess I'll make up one of the cables with the trailing wire, but it just doesn't seem that a brand-new product should need a workaround like that. I don't understand why the beta testers didn't flag this. Ah well......
